Thank you for the replies Phil, Florian.

Why do I use Xinerama?  Good question, I have set up my displays with 
the nVidia X-server settings on the Admin menu and Xinerama was the only 
way I could figure out how to get one virtual desktop. This might be 
another remnant of constant upgrades from 6.1 to last week but using 
that tool  I don't see a way to switch.

I will try removing xorg.conf and seeing if it will fix it.  If not 
where would one find "an xorg.conf for the kmod NVIDIA driver"?

thanks again,

Joe
